Sensex falls to three-month low; risk off adds to budget caution

MUMBAI (Reuters) - The BSE Sensex fell more than 1 percent to its lowest close in three months on Tuesday as blue chips such as ICICI Bank were hit by caution ahead of the 2013/14 budget, although mobile operators rallied on expectations of a cut in airwave auction prices.

Shares in India's wagon manufacturers such as Titagarh Wagons Ltd (TITW.NS) dropped after the government unveiled the railway budget for the year starting in April that was seen lacking big announcements or projects.

Investors are gearing up for the union budget on Thursday, the same day as the expiry of derivatives, which could magnify any volatility.

"Finance Minister is certainly going to show fiscal deficit at lower side. A roadmap to do away with subsidy business would be more important from markets perspective," said Deven Choksey, managing director of KR Choksey Securities.

The benchmark BSE Sensex fell 1.64 percent, or 316.55 points, to end at 19,015.14, marking its lowest close since November 27.

The broader Nifty fell 1.6 percent, or 93.40 points, to end at 5,761.25, posting a three-month closing low as well as the biggest daily fall since July 23, 2012.

Blue chip stocks were among the leading decliners as traders lightened positions ahead of the federal budget. India is also due to post its annual economic report on Wednesday, while final economic growth for the October-December quarter are due on Thursday.

Among other decliners, Ranbaxy Laboratories Ltd (RANB.NS) shares fell 4 percent after reporting a quarterly net loss of 4.92 billion rupees due to provisioning towards costs that might arise due to a product recall in the United States.

Shares in Jet Airways Ltd (JET.NS) fell 11.2 percent, down for a fifth day, on continued concerns about whether the carrier will clinch a deal to sell its stake to Abu Dhabi-based carrier Etihad Airways.

However, shares in Indian mobile network operators rallied with Bharti Airtel Ltd (BRTI.NS) gaining 1.6 percent and Idea Cellular (IDEA.NS) rising 4.1 percent on expectations the government would be forced to cut the reserve price for airwaves after just one potential bidder emerged for a $7.9 billion spectrum sale next month.

Infosys Ltd (INFY.NS) gained 1.4 percent, while Tata Consultancy Services Ltd (TCS.NS) rose 1.5 percent on hopes of incentives for exporters in the 2013/14 budget to be unveiled on February 28.
